Description

Technical Field

[0001] This utility model relates to the field of high-power converter technology, specifically to a detachable cabinet structure and a high-power converter control cabinet containing the same. Background Technology

[0002] With the development of new energy sources, high-power converter technology has also developed rapidly, with its power output increasing. Higher power means a greater number of components and a larger physical size. However, due to site constraints in actual operating plants, it is often necessary to keep the overall size of the high-power converter system within a certain range, and to keep it as small as possible while still meeting functional requirements.

[0003] Meanwhile, high-power converter systems typically contain numerous secondary components, so the efficiency of component installation and wiring in the control cabinet during actual production must also be considered. Conventional secondary component mounting plates are vertically fixed inside relatively narrow cabinets. If the control cabinet accommodating the secondary components is too small, it can only accommodate one wiring worker at a time, significantly reducing manual production efficiency. Conversely, if the control cabinet is too large, it increases the overall size of the high-power converter. Utility Model Content

[0030] Example

[0031] like Figure 1 and Figure 2 As shown, the detachable cabinet structure of this utility model is made entirely of sheet metal and is mainly used in control cabinets for high-power converters. It is known that a high-power converter is a power conversion device that provides rated current and voltage, typically containing one or more power cabinets for primary components and a control cabinet for secondary components. The detachable cabinet structure of this embodiment includes: a mounting plate 1, a top plate 2, a limiting beam 3, and a cabinet 4. The mounting plate 1 is used to mount components and is detachably installed inside the cabinet 4. The top plate 2 is detachably installed on the top of the cabinet 4; as... Figure 3 and Figure 4As shown, after the top plate 2 is removed, the mounting plate 1 is hoisted in and out from the top of the cabinet 4, and the secondary components are installed and removed from the mounting plate 1 outside the cabinet 4. The limiting beam 3 is installed inside the cabinet 4 to assist in the installation and fixation of the mounting plate 1 within the cabinet 4, improving the installation reliability of the mounting plate 1. Centralized production and installation reduce production steps, significantly improving the speed and accuracy of manual installation and wiring in the mass production of high-power converter devices, and further increasing the production quantity of high-power converter control cabinets per unit time.

[0032] like Figures 1 to 4 As shown, in this embodiment, the cabinet 4 adopts a frame structure. To facilitate the demonstration of the installation state of the mounting plate 1 inside the cabinet 4, the front door and side panels of the cabinet 4 are hidden. In other embodiments, the mounting plate 1 can also adopt a front and rear double-plate arrangement to meet the requirement of higher power.

[0033] like Figure 4 , Figure 5 and Figure 6 As shown, the mounting plate 1 includes a mounting panel 11, which has a plurality of mounting holes 15 for mounting secondary components.

[0034] Furthermore, the four sides of the mounting panel 11 are provided with edging 16 to increase the structural strength of the mounting plate 1 and to make the installation and removal of the mounting plate 1 smoother. The edging 16 is provided with multiple mounting holes 15. Among them, the mounting holes 15 of the top edging 16 of the mounting panel 11 are provided with lifting connectors to facilitate the lifting of the mounting plate 1. The mounting holes 15 of the bottom and left and right side edging 16 of the mounting panel 11 are used to connect the limiting beam 3.

[0035] like Figure 6 As shown, the lifting connector includes a hook 12, a washer 13, and a nut 14. The hook 12 has external threads at its lower part and extends through the mounting hole 15 to the inside of the edging 16. The inside of the edging 16 is provided with a washer 13 and a nut 14 to achieve a locking connection between the hook 12 and the mounting panel 11. By setting the washer 13, it is possible to prevent the mounting plate 1 from being pulled off during lifting due to excessive weight, thereby increasing the safety of lifting the mounting plate 1. It is understood that in other embodiments, the mounting plate 1 can also be lifted using a single hook or a hookless method, as long as it can ensure that the mounting plate 1 is lifted smoothly.

[0036] like Figure 7 As shown, the top plate 2 includes a top cover body 21, which is fixed to the top of the cabinet 4. The top cover body 21 has a through hole 25, and a detachable cover plate 22 is provided in the through hole 25. When the cover plate 22 is removed, the mounting plate 1 can be hoisted into and out of the cabinet 4 through the through hole 25, which is convenient and quick.

[0037] like Figure 7As shown, the top cover body 21 has a flange 26 along the length of the through hole 25, and a folded edge 24 along the width of the through hole 25. The folded edge 24 and the flange 26 are welded and fixed together, and after welding, the heights of the folded edge 24 and the flange 26 are flush. The cover plate 22 can be detachably installed in the installation space enclosed by the folded edge 24 and the flange 26.

[0038] Furthermore, a sealing gasket 23 is provided around the side of the cover plate 22. After the cover plate 22 is closed into the installation space formed by the folded edge 24 and the flange 26, the sealing gasket 23 is used to seal the cover plate 22 on the top cover body 21, which can achieve an IP31 dustproof and waterproof rating.

[0039] like Figure 2 and Figure 8 As shown, all four vertices of the limiting beam 3 are connected and fixed to the cabinet 4. The limiting beam 3 includes a limiting vertical beam 31 and a limiting bottom beam 32 arranged perpendicularly to each other. The limiting vertical beam 31 is used to connect the two sides of the mounting plate 1, and the limiting bottom beam 32 is used to connect the bottom edge of the mounting plate 1. Specifically, the limiting vertical beam 31 is provided with multiple mounting holes that match the mounting holes 15 on the side edging 16 of the mounting plate 1. By screwing in fasteners, the side of the mounting plate 1 is connected and fixed to the limiting vertical beam 31. The limiting beam 3 ensures that the mounting plate 1 is installed vertically and centered in the correct position in the control cabinet after being installed back into the cabinet 4.

[0040] Furthermore, the limiting bottom beam 32 is provided with a groove 321 for accommodating the bottom edge of the mounting plate 1. The long side of the limiting bottom beam 32 is provided with a first connecting hole 322, which matches the mounting hole 15 on the bottom edge 16 of the mounting plate 1. Fasteners are screwed into the first connecting hole 322 and the mounting hole 15 to fix the bottom of the mounting plate 1 within the groove 321. The short side of the limiting bottom beam 32 is provided with a second connecting hole 323 for connecting the cabinet 4.

[0041] In this embodiment, the mounting plate 1 for installing secondary components is detachably installed inside the cabinet 4, and the top plate 2 is detachably installed on the top of the cabinet 4. When the top plate 2 is removed, the mounting plate 1 can be hoisted in and out of the cabinet 4 from the top. After being hoisted out, the mounting plate 1 is placed on a horizontal workbench, transforming single-person vertical work into multi-person horizontal platform work. Up to eight operators can simultaneously perform the disassembly and assembly of secondary components around the mounting plate 1, significantly improving the efficiency of secondary component disassembly and assembly, enhancing the labor economy of high-power converter control cabinet production, and without increasing the installation volume of the high-power converter control cabinet. Simultaneously, a limiting beam 3 is installed inside the cabinet 4 to assist in the installation and fixation of the mounting plate 1 within the cabinet 4, improving the installation stability of the mounting plate 1.
